Hi, i was taking a shower and when i finished and turned the hot water off i noticed i could here my combi boiler still working and heating the water. Then when i switched the hot water taps on there is no water coming out of the taps at all. I've had to switch the water fead off to the boiler as it just stays lit. I can hear the water going through the boiler but it wont stop.
Any information would be greatly appreciated.

More information please.
Water still going through your boiler ; is the pressure rising in the central heating?
Was the boiler heating up your radiators When it stayed on?
No water coming out of your hot taps, cold taps all ok?

Hi. Everything else seems to be fine. The heating wasn't on at the time. The boiler pressure remains fine. I have cold water coming out of all taps but no water coming out of Any hot taps at all.
I have turned the cold water feed off because as soon as i turn it on i can hear the water flowing then the pin comes out of the diverter valve and ignights the boiler. It's stays alight as if it thinks I've turned a hot water tap on and called for hot water but there is no water coming out of the taps.

Hi. The boiler is in the kitchen. Had it moved 3 years ago after having a small kitchen extension so all the pipework in there is new. Cant see any sign of leaks upstairs and the floor downstairs idms concrete. Any other way of finding out if you have a leak?

Does the hot supply to the kitchen or downstairs WC run in the concrete?
